Background
The Capelli Road Wastewater Pump Station in Adelaide’s north-west serves a population of around 40,000, receiving flow from nine smaller stations and discharging wastewater to the Bolivar trunk main. The original pump station required complete replacement while ensuring continued operation. The project involved the design and construct of a new submersible wastewater pumping station.
Together with Tonkin, we were able to provide significant cost benefitsc for the project by reducing the amount of concrete required and shortening the time to install the shaft by using precast segments.
Approach and Innovation
Leed worked closely with Tonkin Consulting and SA Water to transform a concept design into detailed For Construction (IFC) drawings for the civil, structural, mechanical, and electrical elements of the project.
An innovative approach replaced the original secant piling wet well shaft design with a cost-effective segmental shaft caisson structure, reducing concrete use and installation time with precast segments. Additionally, the pump station and manholes were lined with SewperCoat, a calcium aluminate cement, for enhanced durability. The station features three submersible pumps in a two-duty/one-standby configuration and a concrete control valve structure for flow redirection between two rising mains.
